At DC per IEC 60947-2 it's rated 15 kA at 60 V (max 72 V operating voltage). Under UL 1077 and CSA C22.2 No. 235 it carries 5 kA, which covers North American supplementary-protector installations. Rated operational voltage is 400 V AC (440 V max for single- or multi-phase operation). The 3-pole design does not switch the neutral conductor. Mounting position is any, and the fastening method is the quick-assembly system — snaps onto DIN rail per the standard 3-module-width footprint (54 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth).
The 5SY6340-7 carries approvals to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No. 235, so it is accepted across European and North American regulatory jurisdictions. The halogen-free and silicon-free construction is relevant for environments sensitive to outgassing — clean rooms, medical device manufacturing, or aerospace-adjacent panels.
Panel integration and environmental limits
Sealable means the toggle can be locked in the off position with a padlock hasp — useful for lockout/tagout compliance without an accessory. IP20 with connected conductors is the protection class; this is an enclosed-panel part, not for wet or outdoor exposure. Ambient temperature range is -40 °C to +75 °C, with derating for humidity: max 95% RH up to 55 °C, tapering to 35% RH at 75 °C.
